The tadalafil-containing medication Vidalista 40 starts to work by inhibiting the activity of an enzyme known as phosphodiesterase enzyme type-5 (PDE-5). The process of erecting a penis involves activating cGMP, which stimulates the penile veins to produce the chemical nitric oxide. This dilation of the blood vessels then allows for a substantial influx of blood flow into the erectile tissues of the penis. When PDE-5 checks this cGMP activity, the entire erection process is rendered ineffective. Thus, Vidalista fights the PDE-5 directly, stopping its disruptive actions and enabling the cGMP to function. In the end, this restores blood flow and helps achieve a strong, long-lasting erection.
